"Greetings on Bhai Dooj, the festival that celebrates the unique bond between a brother and sister," he tweeted. PM Modi is presently on a three-day visit to Britain, from where he will proceed to Anatolia for a two-day meeting of the G-20.

Bhai Dooj is a Hindu festival which is similar to Raksha Bandhan. During this day, sisters pray for the long and healthy life of their brothers.
